A floor-cloth of light Willesden canvas covered the surface of snow or ice in the interior of the tent; performing when sledging the alternative office of a sail. In order to cut snow, neve or ice to pile on the flounce, a pick and spade had to be included in the sledging equip meet. As a rule, a strong, pointed shovel weighing about six pounds answers very well; but in Adelie Land, the surface was so often wind-swept ice, polished porcelain-snow, or hard neve that a pick was necessary to make any impression upon it. It was found that a four-pound spade, carefully handled, and a four-pound miner's pick provided against all emergencies. Our sledges were similar to those of other British Antarctic expeditions; of eleven- and twelve-foot lengths. The best were Norwegian, made of ash and hickory. Others built in Sydney, of Australian woods, were admirably suited for special work. Those made of mountain-ash had the advantage of being extremely light, but the runners wore out quickly on ice and hard neve. Sledges of powellized spotted gum were very strong and stood plenty of rough usage, but were heavier than those procured in Norway. A decking of bamboo slats secured by copper-wire to the crossbars was usually employed. A light bamboo mast and spar were fitted to each sledge. Immediately in front of the mast came the "cooker-box," containing in respective compartments the primus and a bottle of spirit for lighting it, as well as spare prickers, openers and fillers for the kerosene tins, repair outfits and other odd articles. The cooker-boxes were of Venesta board, with hinged lids secured by chocks and overlapped by japara cloth to exclude as much drift-snow as possible. An instrument-box was secured to the sledge near the rear and just forward of a Venesta or aluminium tray on which the kerosene contained in one-gallon tins was carried. In several cases the tray was widened to receive as well a case containing a dip-circle. Rearmost of all was a wooden crosspiece to which the shaft of the sledge-meter was attached through a universal joint. On the middle section of the sledge between the cooker-box and instrument-box, sleeping-bags, food-bags, clothes-bags, tent, alpine rope, theodolite legs, and other articles, were arranged, packed and immovably stiffened by buckled straps passing from side to side. Sledging harness for both men and dogs was constructed of canvas. In the former case, a wide belt of triple thickness encircled the body at the hips, sewn to braces of narrower strips passing over the shoulders, while hauling-rope was attached to the belt behind. The strength of the whole depended on the care bestowed in sewing the parts together, and, since his life might depend upon it, no one made anything else but a thorough job of his harness.
